DC lying about his age?

Mark and DC were being interviewed at Indy today, along with all the other drivers. Did anyone notice when they were talking about age, and when DC mentoned he was 36, someone from the audience yelled out "Thirty eight!" Both DC, the commentators and Mark glanced over for a second, then continued with the interview? If that's true then more power to DC for getting away with it! Off the top of my head, I know Gilles Villeneuve lied about his age, and various minor drivers, anyone else?
